Metal distillation is the thermodynamics
process using the difference of boiling points of metal alloy to separate them
from each other. Usually, the metal of low boiling points is evaporated from
the liquid alloy and later the vapor is condensed in a separate container. In a
distillation system, by setting up condensing elements along the evaporation
passage, the metal of high boiling point gets condensed before taking away
by the vapor. Consequently, low boiling point metal are purified.
Distillation technology is applied
for many industrial sectors to treat scrap/waste generated from industrial
production and daily use household, especially favored by high purity product
application.
Metalcess is a professional company offering metal distillation technology. Metalcess is specialized
in treating waste acid with organics from chemical plant and pharmaceutical factory,
lead-tin alloy, silver froth, crude zinc with lead and cadmium, hard zinc with
aluminum and iron from hot galvanizing, waste acid with selenium and mercury
from acid-making process, and soldering tin from waste electrical and
electronic element, etc.
